Description
Technical field
The utility model relates to a kind of concrete core sample clamping tool.
Background technology
Along with the fast development of construction project, concrete and bituminous concrete are widely applied, and strengthen monitoring and the detection of concrete quality, and ensureing and improve concrete quality, particularly concrete strength problem, is the important topic in current construction project.Core drilling method as current concrete one of detection method intuitively, be a kind of utilize rig from structural concrete core boring sampling to detect concrete strength or to observe the method for inside concrete quality.Utilize drill core test concrete quality, because it is directly perceived, reliable and accurately, be subject to more and more higher attention.But the taking-up that in the drilling core checking process of reality, when clamping and take out core, usually for a certain reason, concrete core sample cannot be complete; There is ponding bottom core and generally also can produce negative pressure, take out difficulty and easily cause core retaining part damaged.
Utility model content
The purpose of this utility model is to provide a kind of concrete core sample clamping tool, there is the position of adjustable pincers cheek, can the core of gripping different-diameter, during sampling, gripping is stable strong, not easily eccentric skidding, ensure that the integrality of the reliability of gripping work and the core of taking-up.
In order to reach above-mentioned technique effect, the technical solution adopted in the utility model is:
A kind of concrete core sample clamping tool, comprise web member and two calipers arranged in specular, it is an entirety that described two calipers are connected by web member, two calipers can rotate around web member, described caliper is equipped with jaw, the pincers cheek and handle, one end of the described pincers cheek is fixedly connected with jaw, the other end of the pincers cheek is fixedly connected with handle, the pincers cheek and handle are formed in one structure, the described pincers cheek is provided with the adjustment hole of several equidistant arrangements, described web member is positioned at adjustment hole place, described jaw is set to tiles structure, two jaws have the one side of inner concave arc surface adjacent, described jaw is provided with spaced flexible rubber bar on inner concave arc surface.
Further, described web member is coupling bolt.
Further, the end activity chain of each described handle is connected to lengthening adjuster bar, and described lengthening adjuster bar can rotate around connecting portion.
Compared with prior art, the beneficial effects of the utility model are: the adjustment hole being provided with several equidistant arrangements by the described pincers cheek, described jaw is set to tiles structure, jaw within it cancave cambered surface is provided with spaced flexible rubber bar, the utility model can the core of gripping different-diameter, during sampling, gripping is stable strong, and not easily eccentric skidding, ensure that the integrality of the reliability of gripping work and the core of taking-up.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to technological means of the present utility model can be better understood, and can be implemented according to the content of instructions, and can become apparent to allow above and other object of the present utility model, feature and advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, described in detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of jaw of the present utility model.
Fig. 3 is the other direction structural representation of jaw of the present utility model.
In figure, each label and corresponding name are called:
1. caliper, 2. web member, 3. jaw, 4. clamp the cheek, 5. handle, 6. adjustment hole, 7. rubber strip, 8. lengthens adjuster bar, 9 turning axles.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further details:
As shown in Figure 1, a kind of concrete core sample clamping tool, comprises web member and two caliper 1, two calipers 1 arranged in specular are an entirety by web member 2 connection, and two calipers 1 can rotate around web member 2; Described caliper 1 is equipped with jaw 3, the pincers cheek 4 and handle 5, one end of the pincers cheek 4 is fixedly connected with jaw 3, the other end of the pincers cheek 4 is fixedly connected with handle 5, the pincers cheek 4 and handle 5 are formed in one structure, the pincers cheek 4 is provided with the adjustment hole 6 of several equidistant arrangements, web member 2 is positioned at adjustment hole 6 place, due to coupling bolt install, dismounting all convenient, web member 2 preferably adopts coupling bolt; Choosing of adjustment hole 6 position can be determined according to the size of core diameter to be got, and like this, just can be reached the object of the core of gripping different-diameter by the position adjusting adjustment hole 6, gripping is simultaneously strong, also not fragile core.As Figure 2-3, described jaw 3 is set to tiles structure, and two jaws 3 have the one side of inner concave arc surface adjacent, and jaw 3 is provided with spaced flexible rubber bar 7 on inner concave arc surface; The design of this globoidal structure and the setting of rubber strip 7, increase contact area and the friction force of jaw 3 and core, avoid eccentric phenomenon of skidding, destroy core bottom in gripping process and form the condition of negative pressure, easier by core clamping taking-up, ensure that the integrality of the reliability of gripping work and the core of taking-up simultaneously.With reference to shown in Fig. 1, arrange turning axle 9 at the end of each handle 5, handle 5 and lengthening adjuster bar 8, by turning axle 9 active link, lengthen adjuster bar 8 and can rotate 0-180 ° of angle around turning axle 9 in the outside of caliper 1; Lengthen the design of adjuster bar 8, kinetic moment is increased, more laborsaving during gripping core; Lengthening adjuster bar 8 can be adjacent to handle 5 to reduce parking space by the used time.
The utility model is not limited to above-mentioned concrete embodiment, and for the person of ordinary skill of the art from above-mentioned design, without performing creative labour, done all conversion, all drop within protection domain of the present utility model.
